MCREventHandler

public class MCRIndexBrowserEventHandler
extends MCREventHandlerBase

This class implements an event handler that reacts on object modify / create / delete events. It basically clears the different classification caches to make sure the number of documents for each classification item is displayed correctly. This has also an impact to the question if a classification item can be expanded to display subitems.
